This invention relates more particularly to Windows of that class comprising a frame in combination with a center pivoted sash or a center pivoted pane; and an object is to 5 provide such windows with screens adapted for practical application to exclude insects when the sash orpane is open, and that will allow the sash or pane to be freely turned on its pivot, and that will permit free ventilation with practical exclusion of insects.

'An object is to provide a strong and light screen adapted to the purpose and to a combination whereby the opening may be automatically screened when the sash or pane is tilte In carrying out the invention with respectto one of its features, Iprovide ametal screen comprising an outwardlyflaring outwardly open hollow rectangular frame. having around its outer, edge anoutwardly extending inwardly bent flange over which wire cloth is bent; said frame forming a chamber of rectangular cross-section open at itsouter side and into wliichsuch wire cloth is rolled or pressed soas to be held therein by its own stiffness and its frictional contact with: the

chamber; said flange affording two angles over which the wire cloth is strained and then crimped into the inner angle of the'chamber.

The invention includes the construction and arrangement whereby a strong rigid stationary screening element is provided for rigid attachment to a stationary frame and. is connected with'a closure and springmeans to press the closure'against thepanes or glass faces of the sash on opposite sidesof the pivotal axis., 40 An object of the invention is economy of with a rigid frame and combining therewith a flexing flange and means to hold the same in position to mainly close the opening between the frame and the pivoted window sash or pane when the main closure is turne to its closed position. 1

Another object is to provide improved means for holding thewire cloth in place.

Another object is to provide an adjustment 'inventionmay appear from the accompany,

time and labor in constructing the screen of the flexing flanges to the muntin bars a of the sash.

An advantage of this invention is that provision is made whereby the flexing flange for a pivoted sash has a strong rigid support in the form of the window screen and is yieldingly held so as to follow the sash without interfering with its pivotal operation.

Thescreen is composed of a flat base or border 7 formed of four sheet metal members disposed in a commonplaneat the top,

bottom and sides and overlapped at. thecorners as at 8 and bent upon each other to form oif-set joints 9,"the overlapped portions being fixed together by well known means, preferably spot welding.

'Prlor to spot welding the plates together, the edges that will be innermost when the frame is. formed,are' bent upward and outwardaway from the inner edges ofthe plates' at a sharp angle offabout l5 to form they flaring walls 10; and the edges of such walls are bent downwardly and outwardly at an angle of about 15 to form the attachment right angle flange 11. The walls 10 and the flanges 11 are mitered at their outer ends and the flarmg frame angular recess therein formed thereby, has its corners united by mitered joints 13 which may be fixed to each other in said well known manner as by spot or other welding. r

The wire mesh or screen 14 is of suitable -'ductile material such as copper wire or galits edges so rolled or pressed into the angular space betweenthe edges of the flaring flange-s and the face of the flat base and such pressure Said is applied as is necessary to stretch the screen mesh drum head tight across the right angle corner of the flaring head or frame formed by V pand the pivoted closure .are constructed to bridge the opening between the fixed screen and the pivoted closure, and is preferably bent in parallelism with its longitudinal edges so that the flexing closure may contact at its edges onl with the faces of the screen and closure an so that such contact will be simultaneous at both edges.

The flat base border isprovided with orifices 15 through which extend oscillatable links shown as cotter-pins 16, the s 17 of which cotter pins fit against the si es of the flat base or border 7 formin a pivotal attachment therewith. The ori ces 15 are arranged along the edge ofthe screen nearestthe pivotal center 18 so that the links form a flexible attachment.

The flexing closure is shown formed of edge of the screen, and the flexing member 19 extends clear across from end to end of'the screen frame, and the oscillating supports 16 which are shown as formed of cotter pins,

are passedthrough holes in the screen frame and through helical springs 22 that are secured as shown, by bending apart the ends of the cotter pins 16 so thatthesprings held by the cotter pins act upon the metal late 19 to force it toward the base 7 ,thus to orce the edge 23 0f the outer flexing member onto the flat smooth surface of the pane 24 ofthe window sash. r

' The screen frame is fixed asby screws 25 to the window frame 1. 1

It is thus seen that the screens are stationary. to the window frame 'on opposite sides thereof, above and below the pivotal axis of the pivoted window and that the flexing closures are constantly spring pressed against the flat face of the panes of the window throughout all positions of the sash, opening, closing and fully closed. 1

The movement between the pane. and. the closure edge issli'ght but is easily accommodated by the springs 22. I I

It is understood that the closures may be of a single length or it maybe made up of sliding sections 20, 20, etc, and that the sash may have a single pane or that the pane may 7 be made up of various sheets held by'muntin bars of the sash. I

Referringto'Figs. 8, 9, 12" and 14, it will be understood that the flexing closures may be notched as at 27, 28,. to fit over the. muntin bars of the window sash and that the flexing closures may be made of sections as at 20, 20 and 20" slidingly connected by joints as at 21 andthat by sliding the sec tions on each other the notches may be brought to register with the appropriate muntin bars 2' of the window sash 2 so as to fit thereon and exclude the flies.

In Figs. 16 and 17 the screen frame is' holding the screen edge is afforded for the reason that the wire screen tucked in between the angular bend as, shown in Fig. 5 exerts its spring pressure between acute angles presented, and the direction of strain of the wire mesh is such as to afford great friction at the acute bend, and the right angle affords a positive straight edge over which the wire mesh sheet is bent, and-such edge holds the stretched sheet truly flat.

I claim:

1. Means for screening an opening between a closure pivoted in a frame and a screen fixed to such frame, and comprising four sheet metal strips fixed together at their ends to form a rectangular base frame and having their inner edges bent to form at one face of the frame a right angle channel frame the webs of the side members of which extend outward from each other, and aslant from the base frame at an angle respectively of 45 degrees, said webs terminating in flange edges spaced from the base flange to form a retainer standing at an angle of about 45 degrees to the face of the base frame; the ends of the flanges being mitered and fixed together to strengthen the frame and to form an outwardly opening channel; a wire mesh stretched over the channel frame and compressed into the rectangular channel, and a spring pressed flexing closure jointed onto one member of the base frame and adapted to contact at its edges with the stationary screen and the pivoted closure.

2. The rigid screen frame constructed with metal strips forming a flat border; the inner edges of the strips being bent from the plane of the frame outward over the border at an angle of about 45 degrees and thence bent at an angle of about 90 degrees outward, and mitered together at the corners and forming an angular frame having an outwardly opening raised strengthening web holding frame spaced from the plane of the border to form a recess to receive wire mesh; and a sheet of wire mesh covering the angular raised frame, and having its edges bent over the strengthening frame, and rolled into the recess, thus forming a rigid screen for the purpose set forth. i

3. The combination with a stationary frame having an opening therethrough, of a rigid screen structure fixed to the frame and extending part way over the opening; a window sash adapted to stationary and adjustable positions to close the opening and pivoted to the frame and provided with a pane forming a plane closure contacting surface; a flexing closure carried by the screen and arranged to yieldingly contact with the contacting surface throughout the stationary and adjusted positionsof the sash; and a spring means acting between the flexing closure and the link to hold the closure against the pane.

4. The combination with an open frame and a closure pivoted thereto to close the opening of a screen frame fixed to the open frame; a flexing closure having an edge to contact with the fixed screen frame and an edge to contact with the-face of the pivoted closure; links adjustably connected to the screen frame and to the flexing closure; and springs carried by the links to press to the edges of the flexing closure against the screen and the pivoted closure. 1

5. The combination with a pivotal closure and a stationary screen having a flange and holes through the flange; of a flexing closure having a frame provided with holes; oscillatable links through the holes of the flange and flexing closure; and spiral springs on the links to yieldingly hold the edges of the flexing closure in contact with the screen flange and the face of the pivoted closure.

6. The combination with a pivotal closure and a stationary screen having a flange and holes through the flange; of a longitudinally bent flexing closure having a frame provided with holes; oscillatable links through the holes of the flange and flexing closure; and

spiral springs on the links to yieldingly hold the edges of the flexing closure in contact with the screen flange and the face of the pivoted closure. 7

In testimony whereof, I'have hereunto set my hand at Los Angeles, California, this 19th day of March, 1929.
